just subtract the like terms from each other
= (10x^4y^5 - 6x^4y^5) + (5xy - 10xy) + (7y^4-10y^4)

Let's subtract the like terms
10x^4y^5 - 6x^4y^5 = 4x^4 y^5
5xy-10xy = -5xy, and
-10y^4 - 7y^4 =-17y^4, so the problem simplifies to
4x^4 y^5 - 5xy - 17y^4

a)open brackets(note that i changed some signs since
- x - =+)
b)rearrange equation to this(i find it helps putting like terms near each other)
10x^4y^5 -6x^4 y^5 +5xy+10xy -10y^4-7y^4
4x^4 y^5+15xy -17y^4.
so how easy it is!
